SASH-FASTEN ER.

SPECIFICA'IJIONI forming part of Letters Patent N o. 257,722, dated May9, 1,882,

Application tiled March 1882.

To all whom it may concern:

Be it known that I, ELEAZEE KEMPsHALL, of New Britain, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in SashFasteners, of which the following is aspecification.

My invention relates to improvements in sash-fastcners of the classwhich are designed to be inserted through one ot the vertical rails ofthe sash, and in which a cast-metal case is screw-threaded on itsperiphery and receives a slotted bolt and spring held within the case bya pin which passes through the sides of the case and through the slot inthat part ot' the body of the bolt which is within the case; and

the objects of my invention are to make a better and more substantialbolt than those generally found in this class and to produce the same ata small cost. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation; Fig. 2,an end 1 view. Fig. 3 is a longitudinal section on line x .r ot' Fig. 2,showing the bolt and spring in elevation; and Fig. 4 is a longitudinalsection on line y y ot' Fig. 2.

I make the case A substantially otcylindrical form, of cast metal, allin one piece, and preferably with a screw-thread 011 its periphery. Ialso form a slightly-projecting jange, c', at`the large end, which, l'orconvenience of description, I will term the outer end.7

The case A is cast hollow to receive the bolt B and spring a, and theorifice in itsouter end, and also that end ofthe bolt, is in the forniof a circle truncated or slabbed off upon two opposite sides, as clearlyshown in Fig. 2. The orice at the inner end ol' the case and the portionof the bolt which lits therein is of less size and of a circular form.

The stem of the bolt is straight and of unil form size from the`shoulder b, against which one end ofthe spring a abnts, to a pointwholi y outside of the c ase, and no part of the inner end of the boltis of any larger size.

(No model.)

The extreme outer end of the bolt is provided with a knob,f, for use asan operatinghandle.

The body ofthe bolt has a longitudinal slot, c, through it at a pointwhich is wholly within the case.

The bolt and spring are inserted from the outer cud and secured thereinby the transverse pin cl, which passes through the sides of the case andthe slot in the bolt. Said pin limits the movement ofthe bolt in bothdirections.

l I make the case ot' a largerdiameter than ordinary bolts ot' thisclass and shorter than the width of ordinary sash-rails.

In order to put the device in place, a hole is bored partly through therail C, Fig. 4, ot' size proper to receive the case A, and the remainderot' the way a smaller hole is bored,large enough to let pass freely thesmallend ofthe bolt, as shown in said Fig. 4. The device is then screwedin place by applying a wrench to the flattened sides ofthe outer endofthe bolt.

I am aware of the Letters Patent to M. L. Kingsley, April 9, 1878, E. B.Beach, September 21,1875, and to Franklin Babcock, September 29, 1868,and I hereby disclaim all that is therein shown and described.

I claim as my invention- A sash-fastener consisting of the solidcylindrical case having a screwthreaded periphery and the liattenedorifice at its outer end, the spring-actuated bolt projecting from bothends of said case and having its outer end of aattened formcorresponding to that of the flattened orifice in the case, and havingalso the longitudinal slot through which the pin passes, substantiallyas described, and for the purpose specified.

ELEAZER KEMPsHALL.
